abstract = "The well-known droop control can ensure real and reactive power properly shared among parallel inverters. However, the effectiveness of droop control is limited in the fundamental-frequency domain and cannot address the harmonic issues. According to previous studies, the harmonic currents generated by nonlinear loads can distort the point of common coupling (PCC) voltage, and negative/capacitive virtual impedances are normally adopted to solve this issue by compensating line impedances. In this paper, it is shown that apart from nonlinear loads, switching deadtime can also introduce circulating current harmonics. To simultaneously suppress the circulating current harmonics and mitigate the PCC voltage harmonics, a novel control strategy is proposed based on virtual harmonic impedance controls. The feasibility of the proposed control strategy is verified through experiments.",
